Evaluation of a new insulation system and checking its integrity in service is a critical process that can involve multiple tests. Doble power factor testing of electrical insulation is one of the recognized and highly regarded procedures in preventive maintenance for electrical power apparatus. The power factor of electrical insulation — or the ratio of the power loss to the volt amperes — measures the quality of the insulation. The better the condition of the insulation, the lower the power factor is. With this in mind, the conscientious field maintenance professional will monitor the power factor of major system components to avert unwanted failures.
